A trio of researchers, two with the Swiss Federal Institute of Technology's Department of Environmental Systems and the other with Climate Service Center Germany, Helmholtz-Zentrum Hereon, say that reducing CO2 emissions ...
(PhysOrg.com) -- Fifty million years ago, the North and South Poles were ice-free and crocodiles roamed the Arctic. Since then, a long-term decrease in the amount of CO2 in the atmosphere has cooled the Earth. Researchers ...

A common type of blue-green algae is finding it easy to adapt to Earth's rising CO2 levels, meaning blue-green algae – of which there are many toxin-producing varieties – are even more adept at handling changing climatic ...
